JSF JSR 168 Portlet problem

We have been struggling to understand how the JSF Portlet bridges work in different versions of the IBM RAD. We are using RAD 7 and the bridge is different from the one we were using with RAD 6.

One saving grace is that the design of the JSF API is quite flexible. ViewHandlers are chained. So I could implement my own ViewHandler and it did not cause any problems for the ViewHandler that the bridge API implements.

I came across this JSR 301 and it looks like this is needed to ensure that the next version of the Portlet spec. works properly with JSF implementations.
